You can set either 68%, 95%, or 99%. The lower the value of the confidence level, the lower the Tau_critical value and accordingly the more suspect observations will be rejected from the adjusted procedure. The default confidence level is 95%. Rejection criterion field - the current criterion for rejecting bad observations. You can select either "By Quality Control" or "Tau Criterion". The default criterion is "By Quality Control". If you select the By Quality Control test, the application will reject the following network components from adjustment with residuals worse than the values set for the current job. These residuals are calculated in the adjustment process for the closed figures and/or for repeated observations in the network: all plane components of the GPS observations and distances and/or horizontal angles of the TS observations for plane adjustment, all height components of the GPS observations and vertical angles of the TS observations for vertical adjustment. If you select the "Tau Criterion" test, the application will reject the following network components from adjustment with a Tau value more than Tau_critical. These residuals are calculated in the adjustment process for the closed figures and/or for repeated observations in the network: all plane components of the GPS observations and distances and/or horizontal angles of the TS observations for plane adjustment, all height components of the GPS observations and vertical angles of the TS observations for vertical adjustment. 20

30 Process Item of the Job Configuration Window The formula for calculating Tau is: Tau = (RES) /?Res, where (RES) - designates the residual calculated for the corresponding component of the observation,?res - the RMS residual error. Note: The value of Tau_critical depends on the number of degrees of freedom and the selected level of confidence in the Confidence Level field. Adjust Dimension - the current dimension for adjustment. You can select either "1D", "2D", "3D", or "Auto". The default dimension is "Auto". 1D: adjustment is performed ONLY in the vertical plane. 2D: adjustment is performed ONLY in the horizontal plane. 3D: adjustment is performed both in the vertical plane and in the horizontal planes. AUTO: the adjustment will run in 1D, 2D or 3D mode for each component depending on presence of control points. Adjustment Type - the current adjustment type. You can select either "Automatic Blunder Rejection" or "Interactive Blunder Rejection". The default type is "Automatic Blunder Rejection". If you select the "Automatic Blunder Rejection" type, the application will automatically reject a blunder observation from adjustment and calculate the final residuals for all adjusted points without the blander component(s). If you select the "Interactive Blunder Rejection" type, the application will interrupt the adjustment process and show a list of blunders. You can manually delete any blunder component from the adjustment or continue the adjustment process. and check boxes: Analyse Repeated Observations - if this parameter is checked (default setting), the application will perform the test of the repeated observations: - A successful test is where the difference between any two repeated observations is less than the horizontal/vertical 21

31 Job Configuration Window observation precision set in the Quality Control Item of the Job Configuration window. - A failed test is where the difference is more than the horizontal/vertical observation precision set in the Quality Control Item of the Job Configuration window. The network adjustment process will be interrupted and the Adjustment Diagnostic window will display. Note: The repeated observations are two or more observations with common start/end names. The observations N1-N2 and N2- N1 are assumed to be repeated. Analyse Identical Points - if this parameter is checked (default setting), the application will perform the test of the identical points: - A successful test is where the coordinate difference for a pair of identical points is more than the horizontal/vertical point precision set in the Quality Control Item of the Job Configuration window. - A failed test is where the difference is less than the values set in the Quality Control Item of the Job Configuration window. The network adjustment process will be interrupted and the Adjustment Diagnostic window will display. Control Tie Analysis - if this parameter is checked (default setting), the application will perform the test of the coordinates of the control points. The Control Tie Analysis test compares the control coordinates with the corresponding coordinates computed using GPS/ TS/DL observations. - A successful test is where the difference is less than horizontal/vertical point precision set in the Quality Control Item of the Job Configuration window. - A failed test is where the difference is more than the value of the horizontal/vertical point precision set in the Quality Control Item of the Job Configuration window. The network adjustment process will be interrupted and the Control Tie Analysis window will display. 22

This coefficient is used to correct the horizontal and vertical distances (measured by Total Station) for refraction and earth curvature. You can select "0", "0.14", "0.2" depending on the measured distance and survey conditions. Traverse Adjustment Type - the current type of traverse adjustment in the Total Station network. Select the following adjustment type: - Least Squares - statistical method for providing a best fit for survey point positions, and detecting and automatic rejection of error measurements (blunders) by minimizing the sum of the squares of measurement residuals. - Compass Rule - this method assumes that the precision in angles or directions is equivalent of the precision in distances. This method works for closed traverses or traverses between two fixed control points. - Unadjusted closure - calculates the network coordinates from the original station coordinates without estimating the accuracy. If the network has duplicate measurements, only one measurement will be used to compute the coordinates. and check box: Use Elevations - This parameter is available when "Compass Rule" or "Unadjusted closure" adjustment type is selected. If this check box is selected, the application will: 24
